Represent on the number line.

Step-by-step solution

Steps of Construction: (i) Draw a line AB such that AB = 6.5 units on the number line. (ii) Extend line AB up to C such that BC = 1 unit. (iii) Find the mid-point of AC and mark it as O. (iv) Draw a semicircle with centre O and radius OC. (v) Draw a line BD perpendicular to AC passing through point B and intersecting the circle at D. (vi) Taking B as centre, draw an arc of radius BD which intersects the number line at E. (vii) Point E represents on the number line l . Therefore, BD = BE = units, with B as zero.
